Title: Avalanche photodetector with deep-level-assisted impact ionization
Inventor: KNIGHTS ANDREW
IPC: H01L31/107
Filed: 2021-06-17
Abstract: Avalanche photodetector devices and methods of use thereof are provided that incorporate deep levels to increase secondary carrier generation via impact ionization under application of a reverse bias. An avalanche photodetector device may include p+ and n+ regions, an intermediate semiconductor absorption region provided therebetween, and at least one semiconductor region residing between the p+ and n+ regions that incorporates deep levels. When light is incident on the device such that the absorption depth of the light extends into the intermediate semiconductor absorption region, a photocurrent is produced under a reverse bias includes both photocarriers generated within the intermediate semiconductor absorption region and secondary carriers released from the deep levels via impact ionization. The deep levels may facilitate an increased sensitivity, relative to a device absent of deep levels, via a deep-level ionization energy threshold that is less than a threshold for conventional impact ionization across a bandgap.
